TriGranit announced the signing of a Power Purchase Agreement (PPA) with UNIMOT, securing the supply of green energy from traceable renewable sources to Signum Work Station for the next three years. Westbridge Advisory Poland acted as advisor during the negotiation of the PPA for the building located in Warsaw’s Mokotów district.
A Power Purchase Agreement (PPA) is a long-term, direct contract between an energy producer and an offtaker, ensuring fixed pricing and guaranteed traceability of the energy’s origin. PPAs are characterised by stability and the ability to hedge costs over the term of the contract, thereby safeguarding investments and minimising price risk for both parties.
A key aspect of the agreement with UNIMOT, Poland’s largest independent fuel and energy group, is the use at Signum Work Station of energy generated from renewable sources – wind and photovoltaic farms located in Poland. The total volume of electricity supplied over the term of the agreement will exceed 12 gigawatt-hours (GWh). According to estimates, optimising electricity procurement at Signum Work Station by relying predominantly on green energy will generate savings exceeding PLN 300,000 compared to previous solutions, driven by more predictable pricing conditions and reduced exposure to market volatility and CO₂-related charges.
The green energy supply agreement will also reduce CO₂ emissions by approximately 8,750 tonnes over the three-year contract period (based on Poland’s emission factor). This is equivalent to the annual emissions generated by more than 1,900 passenger cars, planting approximately 140,000 trees, or avoiding the combustion of over 3.5 million litres of petrol.
Marta Zawadzka, Head of Leasing and Asset Management at TriGranit, said: “Entering into a PPA for Signum Work Station forms part of our long-term strategy to strengthen the building’s value and resilience – both operationally and as an investment asset. We focus on solutions that tangibly enhance cost stability, reduce exposure to energy market volatility, and, at the same time, support the energy transition. Direct access to renewable energy from traceable sources is now one of the key factors driving the competitiveness of modern office developments. For our tenants, this translates not only into predictable and lower energy costs but also into measurable support for achieving their ESG objectives. The PPA provides assurance that they are using genuinely green energy, enhancing the credibility of reporting and stakeholder trust. It is a solution that increases the building’s attractiveness today while safeguarding its value over the long term.”
The preparation of the PPA for Signum Work Station and the negotiation of its terms were coordinated by experts from Westbridge Advisory Poland, a leading energy and sustainability advisor to the real estate sector.
Tomasz Kwiatkowski, Senior Consultant at Westbridge Poland, commented: “By signing the PPA for Signum, TriGranit has secured the majority of the building’s electricity demand with green energy sourced from farms located in Poland. This demonstrates a highly conscious approach to the energy transition, where stability, cost security and a tangible reduction of the carbon footprint were of paramount importance. We are pleased to have advised on this pioneering transaction, which sets a new benchmark for the commercial real estate sector.”
